So when production falls, that's a surprisingly big deal.
Fisheries output dropped by an astonishing 68% in Peru in
November, compared to the same month last year. Output across the
economy grew by only 0.31% from the same month last year, the
slowest pace of growth in years.

Getting hit by a slump in copper prices would be a problem for
the country, as would getting hit by an anchovy shortage. But
getting hit by both at the same time is just adding insult to
injury.
